污水管道工程中深基坑支护与管线保护研究

Research on Deep Foundation Pit Support and Pipeline Protection in Sewage Pipeline Engineering

污水管道开挖过程中的深基坑支护技术与管线的保护是重要环节,论文以广州市白云区城中村污水管道改造工程为例,分析了深基坑开挖过程中存在的难点并提出对策,总结了钢板桩支护与高压旋喷桩2种主要深基坑支护技术及施工要点,给出管线保护建议措施,为城中村污水管道工程施工提供科学参考。

Deep foundation pit support technology and pipeline protection during sewage pipeline excavation are important links. This study takes the sewage pipeline reconstruction project of Chengzhong Village, Baiyun District, Guangzhou City as an example to analyze the difficulties in the process of deep foundation pit excavation and put forward countermeasures, summarized the two main deep foundation pit support technologies and construction points of steel sheet pile support and high-pressure jet grouting piles, and proposed pipeline protection measures to provide scientific reference for the construction of sewage pipeline engineering in the village in the city.
